BACKGROUND OF THE INVENTION
[0001] The present application relates broadly to machines for processing and finishing
knitted products such as underwear, gloves, or socks and, more particularly, to an
apparatus for boarding just-knitted socks for further manufacturing steps. Socks are
typically knitted in a circular knitting machine, there undergoing the knitting process
which transforms yarn into socks. After the knitting process, further processes or
steps are necessary prior to shipping the product to retailers including clipping
loose strands, label printing, pressing, and pairing. Currently, a sock or multiple
socks are typically placed on a sock form, known as a board, which is a foot-shaped,
generally flat member on which the sock is placed for processing. The board forces
the sock into a disposition wherein a toe, body, heel, and leg portion are defined.
[0002] Typically, a sock finishing machine will have several boards arranged in some array
wherein a processing machine will present consecutive boards for sock placement.
[0003] Currently, socks are placed on the boards by hand, which is a labor intensive operation
requiring rapid, repetitive accurate movement. In order to proper board a sock, the
sock must be positioned correctly with the toe portion over the toe portion of the
board and pulled taut over the board for further processing. Since the manufacture
of the sock is automated, and since further processing of the sock is automated, the
person boarding the socks is placed in the unenviable position of being between two
machines. The socks must be boarded at a pace that will keep up with the output of
the production machine and keep up with the demand of the downstream machines provided
for further processing. Further, the position of the socks on the board should be
consistent throughout the consecutive array of socks leaving the knitting machine
for boarding. The stress level for a person boarding socks under these conditions
may be great. The speed required by the machines, in combination with the positioning
requirements, create a difficult situation which is exacerbated by the relentless,
unyielding demand of the machines. Clearly, this manual process requires automation.
However, the process does not easily lend itself to automation due to the manual dexterity
required by the flexibility of the socks in combination with the ability to align
the socks on the form which requires sight and judgment, qualities not typically associated
with machines.
[0004] There is therefore a need for a machine which will properly align the socks on the
form for rapid boarding of consecutive socks.
SUMMARY OF THE INVENTION

DESCRIPTION OF THE PREFERRED EMBODIMENT
[0020] Turning now to the drawings and, more particularly to Fig. 1, an apparatus for automatically
boarding socks is illustrated generally at 10 and includes three major subsystems,
or assemblies, including the delivery assembly 14, the positioning assembly 16, and
the boarding assembly 18. Each subsystem is defined primarily by a separate subframe.
These include the delivery subframe 14, also illustrated in Fig. 2, the positioning
subframe 16, also illustrated in Fig. 3; and the boarding subframe 18, also illustrated
in Fig. 4. Together, the subframes 14,16,18 make a complete skeletal framework 12.
[0021] The skeletal framework 12 is formed from a plurality of vertical and horizontally
extending support members, which may be steel, aluminum, or other suitable material,
and are fixed together in a predetermined arrangement. Collectively, all of the subframes
14,16,18 combine to define a path of movement 21 for one or more socks through the
apparatus 10. As illustrated throughout the drawings, it is preferred that the socks
be boarded singly, but it is anticipated that the present invention is adaptable for
boarding multiple socks either singly on multiple boards in nested pairs on multiple
boards, or in nested pairs on an individual board. It will therefore be appreciated
by the those skilled in the art that the principles involved with the present invention
are susceptible to a wide range of adaptation to fit many different circumstances
requiring automatic sock boarding. It will additionally be appreciated by those skilled
in the art that the term "boarding" is used to describe the placement of one or more
socks onto a sock form, i.e., a foot-shaped form which, from the side, has the general
outline of a foot while being generally flat and planar otherwise. Once boarded, manufactured
socks may then be further processed before ultimate shipment. The processing typically
takes place on the board and may include clipping of loose yarn strands, pressing
or ironing, and imprinting. It is beyond the scope of the present invention to describe
every operation which may be performed on a pair of socks during manufacture. Nevertheless,
it is the focus of the present application to describe and illustrate a component
of the sock manufacturing process heretofore unknown, i.e., an automatic sock boarding
apparatus.
[0022] As will be seen in greater detail hereinafter, the present invention includes several
motors, piston/cylinder arrangements, and an air system, all of which are controlled
by a microcomputer 270, illustrated generally in Fig. 1. It will be appreciated by
those skilled in the art that the microcomputer 270 operates based on commercially
available control software with inputs from the various sensors and outputs to the
various motors, air system, and piston/cylinder arrangements as will be seen in greater
detail hereinafter.
[0023] The three primary subsystems are all interrelated and perform various functions on
socks. The boarding assembly 18 acts to move the sock board into mating engagement
with a sock held by the positioning assembly. The positioning assembly acts to receive
a sock from the delivery assembly and position the sock for engagement by the sock
board. The delivery assembly 14 receives the sock from whatever sock forming operation
occurs prior to intervention by the present invention and delivers the sock to the
positioning assembly 16 in a manner conforming to requirements imposed by the positioning
assembly 16.
[0024] Turning to Figs. 1 and 2, the delivery assembly 14 will be described in greater detail.
As is now known, the delivery assembly 14 accepts one or more socks from a sock source
(not shown) which may be a knitter or other sock production apparatus and delivers
the one or more socks to the positioning assembly 16 in the correct orientation for
further use by the positioning assembly 16. The delivery assembly 14 includes a delivery
subframe 20 including a plurality of vertical support members 22 and horizontal support
members 24 which are arranged in a skeletal fashion to support the various parts which
comprise the delivery assembly 14. A transparent delivery tunnel 26 is provided and
mounted to the upper portion of the delivery subframe 20 and is held thereonto by
clamps 27. The delivery tunnel 26 includes a generally tubular entrance portion 28
which receives the sock from the knitter or other apparatus in a manner which will
be described in greater detail hereinafter and deposits the sock within the semicircular
main body portion of the delivery tunnel 26. A conveyor belt 34 is formed as a conventional,
endless belt and is disposed directly underneath the semicircular portion of the delivery
tunnel 26. A vacuum tube 30 is attached to the delivery tube 26 and is in fluid communication
with a vacuum source (not shown) which will create a vacuum within the delivery tunnel
26. A vacuum integrity door 36 is disposed at an end of the delivery tube 26 opposite
from the entrance end 28. A stop member 48 is formed as a generally flat plate mounted
over the door 36 to prevent excessive vacuum loss by abbreviating the path of movement
undergone by the door 36. The door 36 includes an operating handle 38 and will operate
when bumped from inside by a sock on the conveyor belt 34. The door 36 acts to maintain
the vacuum while allowing the sock to exit the vacuum area on its way out of the delivery
assembly 14. A pair of nip rolls 42,44 are disposed at the delivery end of the conveyor
34 for engagement of the sock moving along the conveyor 34 in order to open the sock
for acceptance by the opening unit, as will be described in greater detail hereinafter.
As seen in Fig. 5, the nip rolls 42,44 include a texturized surface 46 for engagement
with the loosely knit sock fabric. As seen in Figs. 5, 5a, 5b, and 5c, the textured
surface 46 acts to open any sock S passing therethrough such that the open portion
may be engaged by arms 82,84,86,88 associated with the opening unit.
[0025] The nips rolls 42,44 are driven by a belt 40 which is also configured to drive the
conveyor belt 34. An electric motor 60 is provided for the driving motive force. Tension
is maintained on the belt using a conventional spring-type tension system. A bracket
52 is provided and mounted to the subframe 20 and includes a slot 56 mounted with
a pivot pin 58 therethrough. Therefore, the mounting bracket may float and move under
the influence of a biasing spring 54 which is provided to bias the bracket downwardly
thereby bringing an idler roller 57 into contact with the belt 40 thus providing tension.
The spring 54 is fixed to a vertical frame member 22 and the bracket 56.
[0026] As will be discussed in greater hereinafter, a photoelectric sensor 240 is provided
and mounted to the delivery tunnel 26 immediately prior to the conveyor 34 to sense
the presence of the sock which is about to enter the system on the conveyor 34. Wiring
242 provides a route for the electrical signal from the photocell to the microcomputer
270.
[0027] In the above-described manner, the delivery system receives a sock or socks from
a knitter or other apparatus and delivers them to the sock positioning assembly 16
in a useful manner.
[0028] Turning to Figs. 1 and 3, the positioning assembly 16 is illustrated. The positioning
assembly 16 receives one or more socks from the delivery subsystem 14 and positions
the sock for insertion of a sock form, or board, therein.
[0029] Turning now to Fig. 3, the sock positioning assembly is illustrated generally at
16 and is provided for receiving one or more socks from the delivery assembly 14,
positioning and holding sock for insertion of the sock form during boarding.
[0030] Like the remainder of the skeletal frame structure 12, the positioning assembly 16
includes a positioning subframe 70 formed from vertically extending support members
72 and horizontally extending support members 74. Perhaps the most complex subsystem
of the apparatus 10, the positioning assembly 16 includes mechanical devices to receive
the sock from the delivery system, open the sock, place the sock on the sock carrier;
the position the sock for insertion of the sock board.
[0031] To that end, and with reference to Fig. 8, an opening unit 80 is provided. The opening
unit consists of four horizontally extending arms 82,84,86,88 which are paired. Each
arm 82,84,86,88 consists of a generally L-shaped member having a gear 90,92,94,96
attached thereto. The arms are configured for movement in a scissor-like fashion with
driving movement of one arm inducing driving movement of its paired arm through the
respective gears. The arms are configured for horizontal extension in a mutually abutting
relationship prior to opening and, as will be seen, when the sock is fitted thereunto,
the arms are moved and they spread away from each other.
[0032] As seen in Fig. 8, each pair of arms is driven by a piston/cylinder arrangement 116,118
with arms 117,122 extending therefrom and are pivotally attached to each sock spreading
arm 82,84,86,88 using conventional nuts and bolts 110. Movement of the arms 82,84,86,88
of the opening unit is controlled by the microcomputer 270 which receives input from
a photocell sensor 250 which is mounted to the opening unit 80 using a bracket 246.
When the sock is driven onto the opening unit 80, the sensor 250 senses its position,
thereby initiating operation of the opening unit 80. The opening unit 80 is formed
with a slider 112 mounted to rails 114 such that it may move horizontally, back and
forth along the rails 114, under controlled influence. A piston/cylinder arrangement
122 is mounted to the positioning subframe 70 and includes an operating arm 120 projecting
outwardly therefrom. The operating arm 120 is mounted to the opening unit 80 for controlled
sliding movement of the opening unit 80 along the rails 114.
[0033] As previously stated, the opening unit 80 acts to open the sock and position it on
a sock carrier. The sock carrier includes two generally rectangular elongate members
arranged in a parallel, side-by-side relationship. The elongate members 100,102 include
air channels 104,106 formed therein. Further, and with reference to Figure 3, the
carrier members 100,102 extend outwardly from an air plenum 99 which receives air
from an air supply (not shown) through a hose 128 projecting outwardly therefrom.
The entire carrier unit 98 is pivotally mounted to the positioning subframe 70 adjacent
a top portion thereof for rotating movement between a generally horizontally extending
position for accepting socks from the opening unit 80 and a generally vertically downwardly
extending position which positions the sock for receipt of the sock board. A stop
member 46 projects outwardly from each carrier member 100,102 to doff the sock from
the opening unit 80 onto the carrier 98. A spacing 107 exists between the two carrier
members 100,102 with the spacing 107 being wide enough so that the sock board may
fit therebetween. A piston/cylinder arrangement 134 is mounted to the positioning
subframe 70 as seen in Fig. 1. An operating rod 132 projects outwardly from the piston/cylinder
134 and is connected to the carrier 98 by a mechanical link 130 such that inward movement
of the operating rod 132 causes pivoting movement of the carrier 98. As may be expected,
operation of the piston/cylinder 134 to control the carrier 98 is controlled by the
microcomputer 270.
[0034] Once the carrier has been moved to the vertical position, the air system is used
to inflate the sock for ease of acceptance of the sock board. Nevertheless, once the
sock is inflated, it must be positioned with the toe portion correctly aligned to
receive the sock board.
[0035] Once the carrier has been moved from its horizontal orientation to a vertical orientation,
two more operations must be performed on the sock before it is ready to accept the
sock board. Initially, the sock is inflated using air supplied from the air source
(not shown) through the air channels 104,106 within the carrier 98. Secondly, the
sock must be rotated into a position where the toe and heel are properly oriented
for receipt of the vertically descending sock board.
[0036] Referring now to Figs. 3,6, and 6a, the sock rotating system is illustrated and includes
a mounting platform 145 projecting inwardly into the skeletal positioning subframe
16 at a position vertically disposed underneath the carrier 98. An electric motor
144 is mounted to the support member 145 and is configured for driving two horizontally
oriented belts 152,154. As best seen in Figs. 6 and 6a, the two belts 152,154 are
connected using idler wheels 166 to two more belts 150,156 which are configured to
rotate two spaced positioning rolls 136,138. The positioning rolls 136,138 each include
a textured surface 140 for contact with a sock mounted on the carrier 98. The positioning
rolls 136,138 are caused to rotate in the same direction so as to effect rotation
of sock S disposed on the carrier 98 upon contact therewith. This relationship is
best seen in Figs. 7, 7a, and 7b. Since the carrier 98 must be moved into a vertical
position intermediate the rolls 136,138, the rolls must be spaced sufficiently from
one another to allow the carrier 98 to swing into position intermediate the rolls
136,138 and then be moved into a contact position with a sock disposed on the carrier.
This operation is best seen in Figs. 6 and 6a.
[0037] With continued reference to Figs. 6 and 6a, the positioning rolls 136,138 are rotatably
mounted to elongate support members 146,148 which are slidably mounted to a pair of
parallelly extending slider rods 162,164 which are in turn mounted to the overall
support member 145. A piston cylinder arrangement 158 is provided with a control rod
160 attached to one of the roller support members 148. The cylinder 158 is attached
to the other of the support members 146. Therefore, withdrawing working fluid from
the cylinder acts to draw the rod into the cylinder and, due to the mounting arrangement,
acts to draw the roll support members 146,148 toward one another. As illustrated in
Figs. 6 and 6a, this action causes the positioning rolls 136,138 to be drawn toward
one another and toward the sock which is by then positioned intermediate the rolls
136,138. As will be seen in greater detail hereinafter, once the sock is rotated into
the proper position for boarding, the positioning rolls are caused to move in the
opposite direction, i.e., away from one another, and away from the sock disposed on
the carrier 98.
[0038] As previously stated, the sock is inflated and causes to rotate until the toe is
in a predetermined position for receipt of the sock board therein. The position of
the sock is sensed by a photocell 252 mounted to a platform 172 with a sight aperture
174 formed therein. As seen in Figs. 7, 7a, and 7b, the sock rotates across the platform
172 until it is positioned over the photocell 252 as sensed through the aperture 174.
Once the sock is in position, the photocell signals the microcomputer 270 which initiates
an operation to separate the positioning rolls 136,138 from the sock S disposed on
the carrier 98. The photocell 252 is mounted to the underside of the platform 172
using a conventional metal bracket 256 and is in communication with the microcomputer
270 with conventional wiring 254 projecting from the photocell 252. The platform 172
is mounted to a platform subframe 170 which is another skeletal frame formed from
vertical and horizontal support members and positioned underneath the carrier 98.
The platform 172 is mounted to the apparatus 10 using a piston and cylinder arrangement
178 and a support/control rod 176 projecting vertically upwardly from the piston/cylinder
arrangement 178. For stabilization, a vertical stabilization member 182 is formed
as a generally cylindrical rod and includes a slider 180 mounted to the stabilization
member 182 as well as the table 172. In this manner, the platform 172 may be raised
and lowered by the piston cylinder arrangement 178 and stabilized by its relationship
with the slider 180 along the stabilization member 182. As will be seen, as the sock
board descends into the sock, the platform 172 drops away from the sock allowing full
movement of the sock board. One function of the table, other than supporting the photocell
252, is manifest when a loosely knit sock transits the apparatus 10. Since such a
loosely knit sock may not remain inflated even under the influence of constantly applied
inflating air, the platform acts as a support to support the toe of the sock as it
is being rotated by the positioning rolls 136,138 so that the photocell 252 will recognize
such a semi-inflated sock as being in proper position for boarding.
[0039] The apparatus described thus far has been described to receive a sock from a sock-forming
machine and position the sock for receipt by the sock positioning system. The sock
positioning system has then been described as positioning the sock for receipt of
a sock board. The final subsystem is the boarding subsystem 18 illustrated in Figs.
1 and 4. The boarding subsystem 18 includes a boarding subframe 190 which is formed
from vertically extending support members 192 in conjunction with horizontally extending
support members 194. A primary feature of the boarding subsystem 18 is the sock board
204. The sock board 204 is generally L-shaped and includes a horizontally extending
support member 208 and a vertically extending board member 206 projecting perpendicularly
downwardly from the horizontally extending support member 208. A generally sock-shaped
end portion 210 is formed at the distal end of the vertically extending member board
206. The sock board 204 is mounted to the subframe 190 in a configuration which will
allow the sock board to trace a square or rectangular path during boarding operations.
[0040] To that end, it will be appreciated that the sock board 204 must be capable of independent
vertical and horizontal movement. Therefore, to effect horizontal movement, two horizontal,
vertically-spaced slider rods 218,220 are provided and mounted to the subframe 18
and extend between two vertically extending frame members 192. A pair of sliders 222,224
are slidably mounted to the slider rods 218,220 for sliding movement back and forth
along the rods. The upper slider 222 is operationally connected to a piston/cylinder
arrangement 212 which includes a control rod 214 projecting outwardly therefrom and
connected to the upper slider 222. Therefore, actuation of the horizontal piston/cylinder
arrangement 212 will cause the sock board 204 to move backward and forward in a horizontal
plane.
[0041] A vertically-oriented piston/cylinder arrangement 196 is mounted to one of the vertically
extending support members 192 and includes a control rod 198 projecting outwardly
therefrom. The outwardly extent of the control rod 198 includes a wheel 202 mounted
thereto, with the wheel 202 being in contact with a rolling surface 207 formed on
the underside of the horizontally extending member 208 associated with the sock board
204. Accordingly, the sock form 204 is allowed to move horizontally with the wheel
202 reducing any frictional contact which may be present. A second wheel 200 is mounted
to the control rod 198 and is contact with a rolling surface 209 associated with the
vertical support member 192 closely adjacent the control rod 198. This provides a
support for vertical movement of the control rod 198 and, consequently, the sock board
204. Openings are formed in the horizontally extending portion 208 of the sock board
204 through which vertical slider rods 226,228 are attached. These rods 226,228 are
attached to the horizontal sliders 222,224 such that the sock form 204 may move vertically
along these rods 226,228 and horizontally with the sliders 222,224. In this manner,
the sock form 204 can move horizontally to position itself over the then vertically
disposed carrier 98, move downwardly to position the foot portion 210 of the sock
form 204 in a sock, then move horizontally in an opposite direction to move away from
the carrier 98 and then move vertically once again into the initial position. Nevertheless,
it will be appreciated by those skilled in the art that the present invention is configured
for further processing of the boarded sock and, therefore, any manner of sock movement
may be anticipated to achieve the desired result with the sock, once boarded.
[0042] As previously stated, the present invention is controlled by a microcomputer 270
which accepts control signal inputs from the various photocells 240,250,252 to identity
the position of the sock along the path of movement 21. These control signals are
then processed by the microcomputer 270 in a manner which will activate the necessary
piston/cylinder arrangements 122,134,158,178,196,212 to cause various movements throughout
the subsystem to maintain the orderly progression of the boarding process.
[0043] In operation, and with references to Figs. 1a-1l, and with initial reference to Fig.
1a, a sock S is fed into the entrance to the delivery tunnel 26 with vacuum being
applied through vacuum tube 30 to create a negative pressure within the delivery tunnel
26. As the sock S passes by the first photocell 240, it is recognized and the microcomputer
270 causes the conveyor 34 to activate and the sock S is propelled along the conveyor
34 as best seen in Fig. 1b. With reference to Fig. 1c, the sock S abuts the vacuum
door 36 which causes it to open. The opening limiter bracket 48 limits movement of
the door to preserve vacuum integrity for entrance of another sock into the delivery
tunnel 26. Once out of the delivery tunnel 26, the conveyor 34 carries the sock S
to the first pair of nip rolls 42,44. These nip rolls 42,44 will cause the sock S
to exit the delivery assembly 14. With reference to Fig. 1d, the sock S is shown transiting
the distance between the delivery subframe 14 and the positioning subframe 16. As
previously described, this is where the opening unit 80 cooperates with the nip rolls
42,44 to open the sock for positioning on the carrier 98.
[0044] With reference to Fig. 5, the sock S approaches the nip rolls 44,46 on the conveyor
belt 35. The sock S is captured by the nip rolls 42,44 as seen in Fig. 5a, with the
textured surface 46 acting to spread the open portion of the sock as it is advanced
between the rolls 42,44. The arms 82,84,86,88 associated with the opening unit 80
are, at this point, tightly configured against one another to allow the sock S to
be moved thereonto by the nip rolls 42,44. As seen in Fig. 5b, the arms 82,84,86,88
are moved into the sock interior SI. Once the sock S reaches a position underneath
the photocell 250, the photocell 250 senses the position of the sock and transmits
a signal to the microcomputer 270 to actuate the opening unit 80. The microcomputer
270 causes the piston/cylinders 116,118 to move their respective control rods 170,122
to cause the arms 82,84,86,88 to spread mutually away from one another to thereby
open the sock S as best seen in Fig. 5c. Once the opening unit 80 has spread the arms
82,84,86,88 to their maximum separation position, the microcomputer 270 acts to cause
the opening unit piston/cylinder 122 to cause the slider 112 associated with the opening
unit 80 to move away from the receiving position as seen in Fig. 5d. As this occurs,
the sock S will eventually abut stop members 148 as seen in Fig. 5e thereby doffing
the sock from the arms 82,84,86,88 and leaving the sock S retained on the carrier
as seen in Fig. 5e. This relationship is also seen in Fig. 1f. Once the sock has reached
this position, the microcomputer 270 activates the piston/cylinder 134 associated
with the carrier 98 to retract its control rod 132, thereby transmitting this movement
to link 130. Since the piston/ cylinder 134 and the link 130 are pivotally mounted
to positioning the subframe 70, this causes the link 134 to rotate, thereby rotating
the carrier 98 into a vertically extending position with this movement being illustrated
in Fig. 1g.
[0045] As seen in Fig. 1h, the sock S is now in a vertical arrangement and is inflated with
air from the air supply (not shown). Once the carrier 98 has achieved a vertical position,
piston cylinder 158 is activated, thereby drawing the positioning rolls 136,138 toward
one another and in contact with the sock. The positioning rolls 136,138 are also caused
to rotate by activation of the electric motor 144 and since they rotate in the same
direction, the sock is caused to rotate, as seen in Figs. 7, 7a, and 7b. Once the
sock is positioned over the aperture 174 in the platform 172, photocell 252 senses
the presence of the sock S thus emitting a signal to cause the microcomputer 270 to
halt rotation of the positioning rolls 136,138 and the reactivation of piston cylinder
158 to withdraw the rolls from the sock S. This situation is illustrated in Fig 1i.
The positioning of the sock S over the opening 174 and the platform 172 causes the
microcomputer to activate piston/cylinder 112 which draws its control rod 214 inwardly,
thereby causing the slider 222 to move horizontally along the slider rod 218 to move
the sock board 204 into a position over the sock and intermediate the carrier members
100,102. Once this limit has been achieved, and as seen in Fig. 1k, the microcomputer
causes piston/cylinder 196 to withdraw its control rod 198, thereby causing the sock
board 204 to descend into the sock S, thereby boarding the sock S.
[0046] Once the sock S is boarded, as seen in Fig. 1l, the microcomputer 270 causes the
horizontal piston/cylinder 212 to move its control rod 214 outwardly, thereby moving
the sock board 204 and the sock S now associated therewith away from the carrier 98.
Once this occurs, the apparatus 10 may then reset itself to receive another sock and
continue boarding operations.
[0047] It will be appreciated by those skilled in the art that the present invention must
be capable of moving several socks in rapid succession throughout the process in order
to keep pace with the machines which it serves. Therefore, certain portions of the
machine will be reset to receive a consecutive stream of socks while operations are
ongoing in other areas of the apparatus 10. Therefore, simultaneous activity may be
occurring with one sock on the conveyor belt while another sock is being boarded by
the boarding form. Additionally, it is contemplated that multiple carriers may be
used along with multiple sock boards. Further, it is contemplated that other photocells
may be disposed around the platform 172 to sense the position of the tow of the sock
when the carrier reaches the vertical position to cause the positioning rolls to rotate
in one direction or another to achieve the shortest distance to the boarding position
Accordingly, the present invention is capable of modification and adaptation in order
to streamline the process and such modification and adaptation should not be construed
as coming outside the scope and spirit of the present invention.
[0048] By the above, the present invention provides an apparatus for automatically boarding
socks which saves both human labor and time.
[0049] It will therefore be readily understood by those persons skilled in the art that
the present invention is susceptible of broad utility and application. Many embodiments
